@James353365324886,
Right; nothing optimal so far. I explored workaround 1 a bit more. My favorite app is SubtitleEdit. Results below, but quick bottom line: not really an improvement over workaround 2 - unless you already had all your exports. - and maybe not then.
@Mathias Moehl I'm not finding the time the play with Automation Blocks as I would like. Manipulation of captions can be tricky, but what James needs is a method of exporting multiple in/out sections with the sequence time at the in point set to zero for each export. Is that in the library already?
BTW, James, another workaround I tried was resetting the sequence start time for each in/out export, but you can't use a negative.
Subtitle Edit method:
In/out set so that In is 00:12:02. First caption after the in point is 12:11, 9 frames after the beginning of the clip to be exported. Export in/out with sidecar.
To confirm the problem, import the exported clip to PR, make sequence, and confirm that clip starts at zero. Import captions from file using source time, and confirm first caption is at 12:10 - as expected and wrong.
The SRT needs to have its first caption timecode at 00:09. But SRTs use milliseconds, not frames, so assuming 29.97 time, (9/29.97) * 1000 = 300.3.
Open the SRT in Subtitle Edit. The first caption starts at 00:12.375. To make that 00.300, we need to make it 12.075 earlier. So, Synchronization -> Adjust All Times. Enter 12.075, then click "show earlier." You will see the times change. X out the synchronization window. Save the file.
To confirm the fix, import the exported clip to PR, make sequence, and confirm that clip starts at zero. Import captions from the SE edited file using source time, and confirm first caption is at 00:09 - correct and in sync for the whole clip.
